How to compute an FRF
Hello,
I am using 3406D MSO.
Since this model has a DAC, I want to use the signal generator in order to use it as a voltage excitation of a circuit (e.g. using random noise or sine sweep), then measure it with one channel of my PicoScope, as well as measure the output voltage of the circuit under analysis with another channel of Picoscope.
Then compute the frequency response function (FRF) between the input signal and the output signal.
How can I do that?
At the moment I am exporting the time signal into matlab and then compute the FRF in MATLAB but it is very time consuming. It would be better to do it in PicoScope6 environemnt.
Unlikely the software PicoScope6 allows only to compute the spectrum of each channel, but not to compute an FRF between channels.
Thank you and best regards.
Alberto

Thank you so much Benno for your suggestion. I did not found this post.
It seems very promising. I will have a look.
[edit]: wow, this tool is awesome!
